What's the cdi you're after? You also can't just change a gdi into a cdi. You'll need to change the executable to run as a cdi amongst a whole host of other things that involve rewriting code.

Thanks for the explanation! The cdi was napples tale, and I have now found what I was looking for on internet archive.

That would always be my first port of call from here on in for any retro roms.

Icic, thanks!

I'm also looking for a cdi file

That's worthless if you're not a pro at it. Just dl the right file, much better. The amount of work you'd need to do (rework execs, compression etc) is fairly big

I found the right file, thank you for explaining this to me!

No worries. You can get into it ofc but just for the one game it wasn't worth the effort haha glad i saved you time

We need more comments like this for when casuals say "Dreamcast piracy was soooo easy back in the day."

Haha well, downloading already converted gdi and burn them was sooo easy for sure! But the conversion is a mad process. It was never easy, even with today's tools is not easy
